摘要

在各种知觉和眼球运动任务中都观察到了序列依赖效应。这就提出了一个问题,即观察到的这些效应是否具有共同的内在机制。在这里,我们测量了在半可预测环境下,同一组观察者在四项不同任务中的序列依赖效应,其中两项是知觉任务(颜色和方位判断),两项是眼球运动任务(追踪移动目标和瞳孔光反射)。通过利用个体差异,我们寻找了不同任务中序列依赖效应大小的联系。在群体水平上,除了瞳孔反应外,我们在所有任务中都观察到了有吸引力的序列依赖效应。反射性瞳孔光反应罕见地没有序列依赖效应,这表明序列效应需要大脑皮层的处理,甚至需要更高层次的认知。在具有显著序列依赖效应的任务中,序列效应的大小存在大量可靠的差异。我们观察到,在两项知觉任务中,序列依赖性的强弱有明显的关系,但在知觉任务和眼动追踪之间却没有关系。这强调了知觉和眼动控制在处理过程中的差异。所有任务之间缺乏相关性表明,序列依赖性大小的个体差异之间的关系不太可能是由与工作记忆等有关的更普遍的机制驱动的。这表明,在不同的低级知觉任务中,序列依赖效应还存在其他共同的知觉或决策机制。

Individual differences reveal similarities in serial dependence effects across perceptual tasks, but not to oculomotor tasks.

Serial dependence effects have been observed across a wide range of perceptual and oculomotor tasks. This opens up the question of whether these effects observed share underlying mechanisms. Here we measured serial dependence effects in a semipredictable environment for the same group of observers across four different tasks, two perceptual (color and orientation judgments) and two oculomotor (tracking moving targets and the pupil light reflex). By leveraging individual differences, we searched for links in the magnitude of serial dependence effects across the different tasks. On the group level, we observed significant attractive serial dependence effects for all tasks, except the pupil response. The rare absence of a serial dependence effect for the reflex-like pupil light response suggests that sequential effects require cortical processing or even higher-level cognition. For the tasks with significant serial dependence effects, there was substantial and reliable variance in the magnitude of the sequential effects. We observed a significant relationship in the strength of serial dependence for the two perceptual tasks, but no relation between the perceptual tasks and oculomotor tracking. This emphasizes differences in processing between perception and oculomotor control. The lack of a correlation across all tasks indicates that it is unlikely that the relation between the individual differences in the magnitude of serial dependence is driven by more general mechanisms related to for example working memory. It suggests that there are other shared perceptual or decisional mechanisms for serial dependence effects across different low-level perceptual tasks.
